Class Step_5_Scaling_with_Pipeline

  • public class Step_5_Scaling_with_Pipeline
extends java.lang.Object
    MinMaxScalerTrainer and NormalizationTrainer are used in this example due to different values distribution in columns and rows.

    Code in this example launches Ignite grid and fills the cache with test data (based on Titanic passengers data).

    After that it defines preprocessors that extract features from an upstream data and perform other desired changes over the extracted data, including the scaling.

    Then, it trains the model based on the processed data using decision tree classification.

    Finally, this example uses Evaluator functionality to compute metrics from predictions.
